Ground color of dorsal part of body greenish brown, ventral whitish yellow; a black spot at base of caudal fin; 7 dark brown blotches longitudinally arranged in mid-lateral area; black spots on cheeks and operculae, one ventral to the eye; pectoral fins hyaline; white pelvic fins. Pigment intensity variable among localities. 7 or less predorsal scales.

Estimates based on models
Preferred temperature (Ref.
123201): 25.4 - 29.3, mean 28.5 °C (based on 2331 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.4 se; based on diet studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
